## Why Is the Black-Scholes Model Primarily Used for European Options?

The Black-Scholes model assumes that the option can only be exercised at expiration, which aligns with the structure of European-style options. American options, which can be exercised at any time, introduce the complexity of early exercise, which the original Black-Scholes formula does not account for.

More complex numerical methods are required to accurately price American options.

What Are the Limitations of the Black-Scholes Model When Attempting to Price American Options?

Why Are European-Style Options Generally Simpler to Price than American-Style Options?

Why Is the Black-Scholes Model More Suitable for European Options?

What Is the Primary Difference between American and European Style Options in the Crypto Derivatives Space?
